Dejerine-Sottas disease

 [deh″zher-ēn´sot´tahz]
progressive hypertrophic interstitial neuropathy.

De·je·rine-Sot·tas dis·ease

(dĕ-zhĕ-rēn' sō-tahz'),
a familial type of demyelinating sensorimotor polyneuropathy that begins in early childhood and is slowly progressive; clinically characterized by foot pain and paresthesias, followed by symmetric weakness and wasting of the distal limbs; one of the causes of stork legs; patients are wheelchair bound at an early age; peripheral nerves are palpably enlarged and nontender; pathologically, onion bulb formation is seen in the nerves: whorls of overlapping, intertwined Schwann cell processes that encircle bare axons; usually autosomal recessive inheritance; an autosomal dominant form also exists; both forms can be caused by mutations in the peripheral myelin protein gene 22 (PMP22) on 17q or in the myelin protein zero gene (MPZ) on 1q.

Déjérine-Sottas disease

[dezh′ərin sot′əz, -sotäz′]
Etymology: Joseph J. Déjérine, French neurologist, 1849-1917; Jules Sottas, French neurologist, 1866-1943
a rare congenital spino-cerebellar disorder characterized by the development of palpable thickenings along peripheral nerves, degeneration of the peripheral nervous system, pain, paresthesia, ataxia, and diminished sensation and deep tendon reflexes. Diagnosis is made by a histological examination of a peripheral nerve. There is no specific treatment. Also called progressive interstitial hypertrophic neuropathy.

Dejerine-Sottas disease

A severe autosomal dominant or recessive Charcot-Marie-Tooth type demyelinating disorder (OMIM:145900) of early (< age 2) onset, which is characterised by motor and sensory neuropathy with very slow nerve conduction velocities, increased CSF protein concentrations, hypertrophic nerves, delayed age of walking, and areflexia.

Molecular pathology
Defects in PMP22, which encodes peripheral myelin protein 22, cause Dejerine-Sottas disease.

De·je·rine-Sot·tas dis·ease

(dĕ-zhĕ-rēn'-sō-tahz' di-zēz')
A familial type of demyelinating sensorimotor polyneuropathy that begins in early childhood and is slowly progressive; clinically characterized by foot pain and paresthesias, followed by symmetric weakness and wasting of the distal limbs; one of the causes of stork legs; patients are nonambulatory at an early age; peripheral nerves are palpably enlarged and nontender; pathologically, onion bulb formation is seen in the nerves: whorls of overlapping, intertwined Schwann cell processes that encircle bare axons; usually autosomal recessive inheritance.
